SANITARY TOILET SEAT.

Application filed December To all whom t may concern.' l

Be it known that I, Unrssns R. GRANT, citizen of the United States,residing at Alameda, in the county of Alameda and State of California,have invented certain `new and useful Improvements in Sanitary ToiletSea-ts, of which the following is a specification.

The hereinafter described invention comprises a hollow sanitary toiletseat which is expressly designed for use in connection with hospitals,railway cars, and public places, although equally as well adapted forhome use generally, and the object thereof is the production of asimple, light, sanitary and durable closet seat, one which willwithstand the hard usage to which such devices are subjected, and willnot warp, crack or become affected by reason of moisture or the waterstanding in the bow to which it is applied and by Vits construction willafford the user increased room at its forward under side over thatafforded by the seats now universally in use. rlhe improved toilet seatis preferably constructed of two metallic sections or members suitablystamped to the proper shape, the upper member `of the seat havingapplied thereto an outer sanitary coating or "layer Yof hard rubber orother plastic compound. The plastic or rubber covering applied to theupper member of the seat affords a seal for precluding the entranceof`moisture between tlie unity. seam line of the upper and lowersections; gives a proper finish thereto, provides sufficient warmth toprevent undue chilling of the body of the user, and at the same timefurnishes an antiseptic surface for the seat. The members c mpriving theseat are suitably stamped into proper shape for a toilet seat prior tothe union thereof, the inn-er and outer edges of the lower section areupwardly flanged to receive on their inner faces the outwardly curvededges of the upper section.

To comprehend the invention, reference should be had to the accompanyingsheets of drawings, wherein- Fig. l isa front elevation of a closet bowlwith the improved seat applied thereto.

Fig. 2 is a bottom plan view of the seat removed from the closet bowl,disclosing the elastic cushions and their manner of attachment to theseat, and the raised pocket is, 192e. serial No. 681,354.

formed inthe forward portion, of the bottom member of the seat.

Fig. 3 is a plan view of the seat illustratdisposed arrow, particularlyillustrating ther channeled recess at they under side of the forwardedge of the seat.

The numeral l is used to designate any form of a toilet bowl to whichthe improved seat is hinged ;A 2 the bottom open member of the seat; 3the upper open member thereof, and .et the layer or coating of hardrubber applied and vulcanized to the upper member 3. Preferably,l thebottom membery 2 yis stamped from a siiigle sheet of metal, Vand theupper member 3 similarly stamped from `a single piece of metal, thestamped members being of elliptical form. The upper memberr 3 whenstamped is in the form' of a hollow elliptical shell, the upper surfacethereof being gradually downwardly and inwardly curved from. the outeredge portionintermediate the points 5 and 6 to produce the requiredoutline of a toilet seat, conformable to the body of a. user, thematerial between the points 5 and 6 being slightly VVcurved upwardlyinto substantially an ogee swell 6, the swell being sufficient to raisevthe points 6a to a point above the normal Iplane of the remainder oftheseat, the uprise caused thereby tending to properly place the user ofthe seat. The inner edge 6a, as in Fig. 5, is raised to a pointslightlybelow the normal plane of the upper surface of the seat while rthe outeredge on the same line y-fy is in the same plane with the remainingportion of the outer edge.

The said member 2 is from a point inwardly removed from its forward edgeraised and curved upwardly and inwardly on the line 82 to provide aclearance space 8 to the under surface at such portion of the toiletseat. Y

The portion 83 of the member 2 lying forwardly of the space 8 lies inthe same plane as the remainder of the member 2 and overlies the forwardedge 84 of the closet bowl. The inner edge 9 and the outer edge 9 of theupper member 3 of the toilet seat are slightly i outwardly flanged, andthe inner and outer edges l() and 10` of the bottom member upwardlyflanged and crimped onto the flanged edges of the upper member whenuniting one to the other. Y

While preference is given to a crimped seam. union between the inner andouter edges of the members of the toilet seat, it is obvious that thesame may be united in any suitable manner.

hen the said upper and lower members are united, there is produced ahollow toiletseat composed of a substantially flat bottom and an uppermetallic shell section, each of Vapproximately clliptical'forin, theexposed top surface of the upper member or section being shaped toconform to the outline of the body of a user thereof, and 'providedadjacent its forward edge with an uprise or swell. i

The upper elastic, plasticv or hard rubber `covering' l for the uppermember-provides a comparatively warm and antiseptic covering surface forAVthe seat, one which removes the chill which otherwise would resultfrom contact of the body with a metallic surface,

and at the same time provides a surface' which may be readily cleaned.

To the under face of the member 2 the upwardly curved arms `ll areunited, within Vthefi'ee ends of which is mounted the transverse rod l2,which is supported and held by the hinge brackets 13by means o f whichthe toilet seat is hinged to the bowl 1 in the usual manner.

By reason of the seat being lformed hollowy there is secured extremelightness, inasmuch as the members composing the seat may be constructedof thin metal.

The clearance space or depression 8 provided in the under face yof thebottom member of the toilet eliminates the danger of excess foulingadjacent the forward end portion thereof. i

There is provided a lid or swinging cover 14: `for use in connectionwithV the improved toilet seat, the samebeing united in any suitablemanner to the hinge connection between the seat and the closet bowl.Like the seat proper, the swinging lid or cover lll is con* structed ofstamped metal sheets properly provide a hollow substantially ellipticalapair of coopel* seat, one of said sections forming a bottom Y part ofrelatively wide liat form, said bottom part having an area ofsubstantially semi-circular shape extending from the inner edge of theseat forwardly, said area extending upwardly in curved relation from thejuncture with lthe fiat adjacent portion of the part, to the` centralportion of said area at the inner edge thereof and terminating in aplane contiguous to the horizontal plane of the upper edge of the seat,and the other of said sections forming the. upper i part having the edgeportions curved `downwardly from the central portion in a predeterminedmanner, the forwardportion of said upper part being formed with an areaextending substantially `above the horizontal plane ofthe upper edge ofthe seat and spacedfabove the area of the bottom part, saidlast-mentioned area having the portion of greatest height adjacent theinner edge of the seat and having the remaining portions of the areacurving downwardly in all directions into the curvature of the remainingportion of the part to provide abody receiving contour in said seat,vthe edges of said sections being formed into interlocking cooperation toretain the sections in seat forming relation. y i t In testimony whereofI have signed my name to this specification.

ULYSSES R. GRANT.
